Alternatively how can I check the called... (1 Reply)

Did not use 'wait' yet.

killall
KILLALL(1) BSD General Commands Manual KILLALL(1)NAME
killall -- kill processes by name
SYNOPSIS
killall [-delmsvz] [-help] [-u user] [-t tty] [-c procname] [-SIGNAL] [procname ...]
DESCRIPTION
The killall utility kills processes selected by name, as opposed to the selection by pid as done by kill(1). By default, it will send a TERM
signal to all processes with a real UID identical to the caller of killall that match the name procname. The super-user is allowed to kill
any process.
The options are as follows:
-v Be more verbose about what will be done.
-e Use the effective user ID instead of the (default) real user ID for matching processes specified with the -u option.
-help Give a help on the command usage and exit.
-l List the names of the available signals and exit, like in kill(1).
-m Match the argument procname as a (case sensitive) regular expression against the names of processes found. CAUTION! This
is dangerous, a single dot will match any process running under the real UID of the caller.
-s Show only what would be done, but do not send any signal.
-d Print detailed information about the processes matched, but do not send any signal.
-SIGNAL Send a different signal instead of the default TERM. The signal may be specified either as a name (with or without a lead-
ing SIG), or numerically.
-u user Limit potentially matching processes to those belonging to the specified user.
-t tty Limit potentially matching processes to those running on the specified tty.
-c procname
When used with the -u or -t flags, limit potentially matching processes to those matching the specified procname.
-z Do not skip zombies. This should not have any effect except to print a few error messages if there are zombie processes
that match the specified pattern.
ALL PROCESSES
Sending a signal to all processes with uid XYZ is already supported by kill(1). So use kill(1) for this job (e.g. $ kill -TERM -1 or as root
$ echo kill -TERM -1 | su -m <user>)
EXIT STATUS
The killall command will respond with a short usage message and exit with a status of 2 in case of a command error. A status of 1 will be
returned if either no matching process has been found or not all processes have been signalled successfully. Otherwise, a status of 0 will
be returned.
DIAGNOSTICS
Diagnostic messages will only be printed if requested by -d options.
SEE ALSO kill(1), sysctl(3)HISTORY
The killall command appeared in FreeBSD 2.1. It has been modeled after the killall command as available on other platforms.
AUTHORS
The killall program was originally written in Perl and was contributed by Wolfram Schneider, this manual page has been written by Jorg
Wunsch. The current version of killall was rewritten in C by Peter Wemm using sysctl(3).
